A blog sharing information about materials presented to children on climate, highlighting those intended to frighten or mislead, and those which seek to inform and inspire rather than to recruit, even the very young, for an ill-founded political campaign around the threat of CAGW. A campaign which is irresponsible, destructive, divisive, and degrading.

'First, the non-climatic effects of carbon dioxide are dominant over the climatic effects and are overwhelmingly beneficial. Second, the climatic effects observed in the real world are much less damaging than the effects predicted by the climate models, and have also been frequently beneficial.'

For the Climate Classroom Wall: two plots, two revelations - nought for the comfort of climate alarm campaigners

The valiant viscount, Christopher Monckton draws attention to this plot, and writes 'This graph is highly topical. It is right up to date. Remote Sensing Systems, Inc. (RSS) is one of the two satellite-based datasets (the other is the University of Alabama at Huntsville (UAH). And RSS is one of the five standard global temperature datasets, which include the two satellite datasets and the three terrestrial datasets – Goddard Institute for Space Studies (GISS); the Hadley Centre/CRU dataset, version 4 (HadCRUT4); and the National Climatic Data Center (NCDC). As this month, RSS is usually the first to report, and its latest monthly value, for February 2014, became available just hours ago. '

From the invaluable C3 website, which notes 'Scientists associated with the UN's IPCC predicted that the huge consumer/industrial emissions of the modern era would cause not only "unprecedented" global warming but also dangerous "runaway" warming, which would then produce "tipping point" climate change.

The climate science consensus today is that these speculative climate forecasts, based on flawed computer models, did not happen and expert analysis of the gold-standard of temperature datasets (the UK's global HadCRUT4) confirms it.

As this adjacent chart reveals, modern warming increases over the last 60 years don't even match the warming increases of the prior 60-year period, when earlier human emissions were just a fraction of contemporary amounts.'

Observed and Expected Temperatures

Scafetta Model
This displays a forecast made by Scafetta using a simple model combining various cycles which have been observed in temperatures, together with some 'adjustment for global warming'. His forecast has the light blue background. An IPCC 2007 'projection' is shown with a green background. The bold red-then-blue line is the HadCRUT calculation of a global mean temperature, with blue line connecting the most recent results. (Source: Tallbloke's blog).
